Southern blot analysis


Southern blot analysis
a technique for identifying a specific form of DNA in cells. The DNA is extracted from the cells and restriction enzymes used to cut it into small fragments. The fragments are separated and a gene probe known to match the DNA fragment being sought is used. Compare Northern blot analysis, Western blot analysis.
